Answer:
Sampson gains 3.967 kilograms from November to February.
Step-by-step explanation:
Given:
Actual Weight on November 15 = 2.49 kg
On December 15, he weighed 1020 grams more
Since 1000 grams = 1 kg
Weight on December 15 = 1020 grams = 1.2 kg
Hence Weight gained from November 15 to December 15 = 1.2 kg
On January 15, he had gained another 2200 grams
Weight on January 15 = 2200 grams = 2.2 kg
Hence Weight gained from December 15 to January 15 = 2.2 kg
On February 15, he had only gained 0.567 kilograms.
Weight on February 15 = 0.567 kg
Hence Weight gained from January 15 to February 15 = 2.2 kg
Total weight gained from November to February = Weight gained from November 15 to December 15 + Weight gained from December 15 to January 15 + Weight gained from January 15 to February 15
Total weight gained from November to February =
Hence Sampson gained total weight of 3.967 kg from November to February.
We are given that the angle a is the right angle. So let us work from this.
ab = 12 (the vertical side of the triangle)
bc = 13 (which if drawn can be clearly observed to be the hypotenuse) = the side opposite to angle a
ca = 5 (the horizontal side of the triangle)
Since we are to find for the cosine ratio of angle c or angle θ, therefore:
cos θ = adjacent side / hypotenuse
cos θ = ca / bc
cos θ = 5 / 13
Check out the attached image below for the illustration of the triangle.
